CRUSHER.

SPECIFICATION forming part of Letters Patent N o. 668,651, datedFebruary 26, 1901.

Application filed. May 2, 1900. Serial No. 15,190. (No model.)

To all whom it may concern:

Be it. known that I, WILLIAM H. LINeo, a citizen of the United States,residing at Hollyville, county of Sussex, and State of Delaware, haveinvented a certain new and useful Improvement in Crushers, of Which thefollowing is a specification.

My invention relates to a new and useful improvement in Crushers forpulverizing ore or like material or grinding corn and the like, and hasfor one object to providean exceedingly simple and effective device ofthis description capable of being operated by hand by a simplereciprocating movement.

A further object of my invention is to provide means for adjusting themovable member relative to the stationary member, so as to determine thedegree to which the material is crushed or ground.

With these ends in View this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled inthe art to which this invention appertainsmay under stand how to make and use the same, the

construction and operation will now be described in detail, referring tothe accompanying drawings, forming a part of this specification, inwhich- Figure 1 is a central section of myimproved Crusher, showing itsecured to a beam or other suitable surface; Fig. 2, a plan view of thedevice; Fig. 3, a section at the line 0c a; of Fig. l; Fig. 4, a bottomplan of the crushingjaw; Fig. 5, a detail section of one of theeccentric bushingsand the means for holding itin adjustment, and Fig. 6an elevation of one of these bushings.

In carrying out my invention as here embodied, A represents the body ofthe device, which is made in the shape of a trough, having formed in thebottom thereof rows of teeth B, which are concaved, as indicated at C,each row of teeth being notched, as shown at D, these notches varying,as shown at E. In this boX is fitted the crushing-jaw F, which ispivoted, as will be hereinafter set forth, so as to be oscillated to andfro therein. This jaw is curved to correspond with the curvature in thebottom of the body and has formed thereon the rows of teeth G, which arealso notched, as indicated at H and I, to correspond with the notchesformed in the rows of teeth B. The rows of teeth upon the jaw match intothe spaces between the rows of teeth in the body, so that when they areoscillated the notches in each set of teeth will bring about a crushingand grinding action, as well a grad ual feeding downward of thematerial, until it is finally ejected from the lower end of the devicein the state of disintegration desired. The upper portion of the jaw isformed upon a straight line and matches the straight portion of thebottom of the body, as clearly shown in Fig. 1, and

thereby acts in conjunction with the body as a hopper or receptacle, aswill be readily understood. The shape of the teeth is clearly shown inFig. 4, and they readily act to draw the material in during theoscillations of the jaws,first roughlycrushing the same,and thengradually crushing and grinding it iiner and finer until the desiredlimit is reached.

The jaw is pivoted Within the body in the following manner: J is a rodor shaft which is passed through the lugs K, formed upon the jaw andinto the bushing L, set in the posts M, projecting upward from the body.The bearings in these bushings are formed eccentric relative to theperipheries thereof, so that by revolving the bushings the shaft will beraised or lowered, as the case may be. The periphery of each of thesebushings is polygonal, as indicated at N, and is itted in acorresponding hole formed in the standards M, which will lock thebushings in any adjustment-that is to say, when the bushings are turnedupon their axis for the raising or lowering of the shaft and again setwithin the polygonal-shaped holes they will be prevented from turningupon their axis until withdrawn therefrom, and in order that they mayAnot be accidentally displaced a strap O is provided for each bushing andis adapted to fit over the edges of the standards, as indicated at P.When these straps are invplace, the bushings cannot be withdrawn fromtheir bearings, but when it is desired to adjust the bushings the strapsare removed,`.the bush- IOO ings withdrawn from their bearings, turnedto the proper degree, and reinserted in the holes and the strapsreplaced, thus providinga positive adjustment for the shatt, whichcannot be displaced.

A handle Q is provided for the oscillation of the jaw and may be made ofwood or any other suitable material and is fitted between the ears R andthe posts K and held in place by a pin S being passed through said earsand the handle, while the shaft .I serves to hold the lower end of thehandle in place. This permits the handle to be moved when occasionrequires, thus facilitating the shipping or storing of the device.

Suitable screws T are utilized for securing the crusher to a beam orother suitable surface at the proper angle to perform the Work, thisangle being illustrated in Fig. l. In practice the material is placed inthe upper end of the crusher and the handle Q oscillated to and fro,which will cause the curved portion of the jaw to ride in the concentricconcaved portion of the body, while the straight portion of said jawwill be caused to move back and forth relative to the body, thus roughlycrushing the material, after which it will be gradually fed downward andreduced, as before set forth.

Atapering plate Q is slidable on the lever Q and is slotted to receivethe studs q, by which the movement of said plate is limited. The plateis provided to engage the pivot of the jaw to prevent wear on the leverwhen wedged thercagainst and swung.

One of the principal advantages of my improvement is its exceedingsimplicity and the fact that there is but one moving part therein whichmay be easily removed for repairor substitution, if occasion requires,and as the device may be almost wholly made from castings with little orno finish the cost of manufacture is relatively small.

Having thus fully described my invention, what I claim as new and usefulis- 1. In a device of the character described, a body having teeth, ajaw working in conjunction with the body and means for pivoting the jaw,an operating-lever pivoted to the jaw and a plate slidable on the leverand engaging the pivot of the jaw, substantially as described.

2. In a device of the character described, a trough-shaped body, rows ofteeth formed on the bottom thereof, said teeth being concaved andnotched, a jaw curved to the contour of the bottom of the trough, rowsof notched teeth formed on the jaw matching into the space between therows of teeth in the body, the upper end of the jaw being straight tomatch a straight portion of the trough, lugs formed on the jaw, bushingsset in posts of the body, eccentric bearings for the bushings, theperiphery .of each bushing being polygonal and fitting in correspondingholes in the standards, a strip for each bushing fitting over the edgesof the standards, an operating-lever pivoted to the jaw. a taperingplate slidable on the jaw and wedged under the pivot of thejawsubstantially as described.

3. In combination, a trough, a jaw acting in conjunction therewith andmeans for pivoting the jaw comprising lugs formed on the jaw, bushingsset in posts ofthe body, eccentric bearings for the bushings, theperiphery of each bushing being polygonal and tilting the correspondingholes in the standards, and a strip for each bushing fitting over theedges of the standard substantially as described.

In testimony whereof I have hereunto afiXed my signature in the presenceot' two subscribing witnesses.
